ISTQB Risk-Based Testing Strategies 2

Question 1

In risk-based testing, what does 'risk exposure' represent?

Accepted Answer

The product of likelihood and impact of a risk

Answer

Risk exposure is calculated as the product of the probability (likelihood) that a risk will occur and the impact it would have if it did occur.

Question 2

Which activity is MOST closely associated with the 'risk identification' phase in risk-based testing?

Accepted Answer

Brainstorming sessions with stakeholders to list potential risks

Answer

Risk identification involves techniques like brainstorming, expert interviews, and checklists to enumerate potential product and project risks.

Question 3

A project team discovers a new critical defect late in the cycle affecting a medium-risk module. What should they do FIRST under a risk-based approach?

Accepted Answer

Re-assess the module's risk level given the new information

Answer

Risk-based testing requires continuous risk re-assessment; a critical defect in a medium-risk module may elevate that module's risk level and change testing priorities.

Question 4

Which of the following BEST describes 'product risk' in the context of ISTQB risk-based testing?

Accepted Answer

The possibility that the software will fail to satisfy stakeholder needs

Answer

Product risk relates to potential quality problems in the software itself, such as failures that harm users or the business, as opposed to project risks which affect the project process.

Question 5

When using a risk matrix to prioritize testing, a feature is rated 'high likelihood' and 'low impact.' Where should testing effort be directed relative to a 'low likelihood, high impact' feature?

Accepted Answer

More effort on the low likelihood/high impact feature

Answer

Although both cells may yield similar risk exposure, high impact risks often receive more attention because their consequences are more severe if they occur.
